The twenty-first century will inevitably be shaped by health. We would do well to understand the challenges and opportunities this entails.

In this essay, physician Alice Desbiolles warns against a technocratic, disciplinary vision of public health, arguing instead for a holistic, multidisciplinary approach: one that goes beyond quantitative indicators alone. She invites us to confront, with clarity, the many health-related, ecological, and democratic challenges that the future will certainly have in store.
